Nearly 50 people have been arrested at protests in Ferguson, Missouri, over the shooting of an unarmed black teenager two months ago.
Civil rights activist Cornel West was among those held after he led a march to the police station. Riot police lined up outside the building and arrests were made when people tried to break the line. The protests were part of four days of events called "Ferguson October", which calls for an end to police brutality.
Demonstrators also demanded that charges be brought against the white officer who killed Michael Brown, 18, at the start of August.
The protest began on Monday morning when demonstrators marched with arms joined from Wellspring Church to the police station in heavy rain.
